Open source Stirling engine

Open source Stirling engine

Tom B.
A simple, low cost and scalable Stirling engine. Experimental dual (4 cylinder) alpha configuration, utilizing flexible piston seals (plastic bags, not shown) and piston driven cam on main shaft. Designed to be made using off the shelf extruded plastic and in the future, aluminium components. Because shaft is a straight rod, it easily extented by 4 cylinder sections. The flexible seal make the piston friction very low and allows low cost cylinder and piston to be used, because clearences are very loose. Operating temperature range can be changed by changing diameter and hole location. Prototype is still under construction. See link for status. #alpha #engine #Stirling
